Description
GPT-Realtime-2.1 is an OpenAI realtime model designed for advanced voice-agent and speech-to-speech AI applications. It improves on GPT-Realtime-2 with stronger alphanumeric recognition, better silence and noise handling, and more natural interruption behavior. The model supports text, audio, and image inputs, while producing text and audio outputs for interactive realtime experiences. Developers can use GPT-Realtime-2.1 across endpoints such as Chat Completions, Responses, Realtime, realtime translation, realtime transcription sessions, and related OpenAI API workflows. The model supports function calling, configurable reasoning effort, instruction following, and reasoning token support for complex voice-agent tasks. Its 128,000-token context window and 32,000-token maximum output make it suitable for longer conversations and more detailed realtime workflows. GPT-Realtime-2.1 does not support video, structured outputs, fine-tuning, or predicted outputs according to OpenAI’s current documentation. Pricing starts at $4 per 1 million text input tokens and $24 per 1 million text output tokens, with separate pricing for audio and image tokens. By combining realtime audio interaction, reasoning, tool use, and multimodal input, GPT-Realtime-2.1 helps developers build responsive AI agents for support, sales, operations, translation, transcription, and interactive voice applications.
Description
Gemini 3.8 Live is a native speech-to-speech AI model from Google DeepMind designed for low-latency conversational agents and real-time voice applications. The model can reason and execute tasks while maintaining the natural flow of an audio conversation. Its asynchronous function calling capability allows external APIs and tools to run in the background without forcing the agent to stop speaking while it waits for results. Developers can combine streamed audio with structured information through incremental content updates, allowing responses to adapt as new data becomes available. Visual context support enables applications to ground conversations in live images or video so agents can understand both what users say and what they are looking at. Gemini 3.8 Live supports more than 97 languages and is designed to maintain consistent accents across multilingual experiences. The model also emphasizes alphanumeric precision for accurately understanding information such as account identifiers, confirmation codes, technical values, and claim numbers. A related Gemini 3.8 Live Extended Thinking model adds configurable reasoning for more complex, multi-step tasks while continuing to interact with the user. Gemini 3.8 Live is available through the Gemini API, Google AI Studio, and integrations with real-time development platforms such as LiveKit, Pipecat, Agora, LangChain, and Vercel.
